Don't think I've personally played in live games where there's been cheating going on (though it's not always easy to tell), but there's all kinds of cheating and you can bet that some of it still goes on even in modern casinos.
Player collusion is the most obvious example. As is chip dumping or replacement in tournaments. Hell, there was a major tournament that got shut down for that not long ago after they found a heap of tournament chips in someone's room.
Card marking is something that can happen too. Casinos are pretty good at spotting it and changing the decks out, but that doesn't stop people from trying from time to time. There was an example of this apparently from the $50K HORSE tournament at the WSOP
not too many years ago.
And that's before we even get into bar leagues or home games where security is basically non-existent.
Long story short, if you're playing in a casino then you're probably as safe as you can reasonably expect to be. But it still pays to be informed and alert.

Oh dear - that was baccarat
/ punto banco, not poker, and the jury's still out (literally) on whether or not what he did was actually "cheating" or not.
